MAP-CASE.

SPECIFICATION forming part of Letters Patent N 0. 405,666, dated June18, 1889. Application filed January 25, 1889. Serial No. 297,534. (Nomodel.)

To aZZ whom it may concern:

Be it known thatwe, GEORGE B. HEOKEL and GEORGE JAMES, both of Chicago,in the county of Cook and State of Illinois, have invented a new,useful, and Improved Map-Case, of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,forming a part of this specification, in which Figure 1 is a front viewof our improved map-case, showing the same open and the maps placedtherein ready for use. Fig. 2 is a vertical sectional view of the same,taken upon the line a: at, Fig. 1, viewed in the direction of the arrowthere shown. Fig. 3 is an enlarged front view in detail of a portion ofsaid case, showing the fastening mechanism. Fig. 4: is ahorizontalsectional view upon the line 2 y, Fig. 2. Fig. 5 is a sideView in detail of the notched looking-plate attached to one end of thecase for securing the mapspindle. Fig. 6 is an inside face view of thesecondary plate. Fig. 7 is a sectional view 7 Fig. 5. Fig. 8 is an endview in detail of the map-roll and the spindle which engages thelocking-plate, and Fig. 9 is a side view showing a modified form oflocking-plate.

Like letters of reference in the different figures indicate like parts.

The object of our invention is to provide a case for maps which maybesimple and compact in its construction, may be closed to protect themaps when not in use, with which they may be detaohably connected, andin which they maybe so arranged as to be readily selected and exhibitedfor examination.

To these ends our invention consists in the combination of elementshereinafter described and claimed.

Referring to the drawings, A represents a map-case,which consists of anoblong shallow box, to the bottom of which is hinged a door B. In theends of the case, respectively, we

secure metal plates C D, for the reception of the map-roller spindles.E, Figs. 2, 3, 4, and 8, represent the roll to which the maps 0 areattached in the usual way. A stick 6' is Se cured to the bottom of themap for the purpose of handling and to stiffen and protect it. Upon oneend of each of the rollsE is rigidly attached the usual round spindle ewhile upon the opposite end is the usual loose spindle, which isjournaled in the roll itself and provided with a spiral spring and theprotruding end 6 of which is polygonal in form, like that of theordinary curtain-roll. The plate C is provided with a series ofperforations 0, Fig. 6, for the reception of the spindles e while slots(1, of the width of the fiat part of the spindles e are formed in theplate D, for the reception of said spindles. Preferably placed oppositethe slots cl, and secured to the plate D in any well-known way aresprings cl, which rest flatly against said slots, as clearly shown inFigs. 2, 4, 5, and 7. Said springs are by preference provided withperforations 61 for the reception of the spindle e which is adjusted inthe following manner: The spindle e is first inserted in one of theperforations 0, when the spring cl is bent as shown by the dotted linesin Fig.

4.. This permits the spindle e to slide back in the slot (1 until itreaches the perforation d in the spring d, When the recoil of the springlocks the spindle e in place. The map may then be raised or lowered,rolled, or unrolled by simply pulling upon or releasing the sticks 0.Each of the plates C D is provided with a series of notches e for thereception of the sticks 6, so that when said maps are rolled the stickse fit in order in said notches, as shown in Figs. 1 and 5.,which avoidsconfusion and enables any map to be selected at sight while rolled bysimply placing a label upon the stick. WVhile the springs (1 may beriveted or otherwise attached to the plate D, we prefer to attach themin the following manner: Upon the rear of the plate D we form a bead (1Figs. 2, 4-, 5, and 7, and the spring (1 is bent, as shown at (1 to slipover and fit upon said bead, as' clearly shown in Fig. 7, which lessensthe cost of construc tion.

In Fig. 9 we have shown a modification in which the spring is riveted tothe plate at 61 and a detent f is formed thereon, as shown, in lieu ofthe perforation (l and as the mechanical equivalent thereof.

Having thus described our invention, we 10o claim-- 1. Theco1nbination,\vith a map=case, of the roll-holding plates 0 D, havingperforations tions (1 to conform to said beads, substanand slots 0 cl,respectively, suitable rolls,spintially as shown and described. dles ee, and springs in operative connec- In testimony whereof We have signedthis tion with said slots for normally locking said specification, inthe presence of two subscrib- 5 spindles e in place, substantially asshown ing Witnesses, this 15th day of January, 1889. 15
